Lenses: These are curved optical glass or plastic elements that focus or disperse light beams by refraction. Common laboratory lenses include convex (converging) and concave (diverging) types used in microscopes, spectrometers, and other optical devices. They have precise curvatures and coatings to minimize distortions and maximize light transmission. Mirrors: Laboratory mirrors are flat or curved reflective surfaces made of glass with a reflective coating, often aluminum or silver. They redirect, focus, or split light beams in optical paths for experiments and instruments. Types include plane mirrors (flat surface) and concave or convex mirrors for focusing. Materials & Coatings: High-quality optical glass with anti-reflective coatings is preferred for clarity and durability. Coatings reduce glare and improve performance for specific wavelength ranges. Uses: These components are integral to various scientific applications such as microscopy, laser optics, spectroscopy, and imaging techniques, enabling precise control of light for measurement, visualization, or analysis. Laboratory lenses and mirrors are carefully manufactured to exact standards for optical clarity, mechanical stability, and chemical resistance to meet the needs of scientific research and testing.
